LAMMPS (27 Nov 2018)
  using 1 OpenMP thread(s) per MPI task
# This example demonstrates the use of various fix qeq variants with pair reax/c
# You can comment in/out various versions below
#
# 1) Fix qeq/shielded generates the same results compared to fix qeq/reax when
#    used with pair_style reax/c, provided that the QEq parameters are the same.
#
# 2) Fix qeq/point and fix qeq/dynamic generate comparable results provided that
#    the QEq parameters are the same.  These two styles can also be used with
#    pair_style reax/c.
